The code is correct - try with another server. I tested it with a
LightHTTPd server and worked fine.
Gabriel...
I found a bunch of servers to test it on. It fails on every server I
could find (sans one).
Here's the ones it fails on:
slashdot.org
hotmail.com
godaddy.com
linux.com
lighttpd.net
I did manage to find one webserver it succeeded on---that is
kenrockwel.com --- a domain squatter with a typoed domain of one of my
favorite photographer's websites (the actual website should be
kenrockwell.com)
This squatter's site is indeed running lighttpd---but it appears to be
an earlier version, because the official lighttpd site fails on this
test.
We have all the major web servers failing the test:
* Apache 1.3
* Apache 2.2
* Microsoft-IIS/6.0
* lighttpd/1.5.0
So I think it's the python side that is wrong, regardless of what the
standard is.
I've found the problem. The zlib header is missing (2 bytes), data begins
right with the compressed stream. You may decode it if you pass a negative
value for wsize:
try:
data = zlib.decompress(data)
except zlib.error:
data = zlib.decompress(data, -zlib.MAX_WBITS)
Note that this is clearly in violation of RFC 1950: the header is *not*
optional.
BTW, the curl developers had this same problem some time ago
<http://curl.haxx.se/mail/lib-2005-12/0130.html> and the proposed solution
is the same as above.
This is the output from your test script modified as above. (Note that in
some cases, the compressed stream is larger than the uncompressed data):
